I’m trying to easily get better accuracy in remote locations using an iPhone and Avenza Pro. My office has an old bluetooth enabled GPS Pathfinder Pro with a VGA port and a software CD–but my laptop supports neither. David, you mentioned connecting to an antennae via Trimble app, which app and would it work for my situation? If not, I’m happy to buy a different antennae but need recommendations on simple and effective options. Thanks for any help you send my way.
